I think this answer is wrong. It should be 0.2 seconds, according to the definition of a Time Period in oscillatory motion.

Ans 9:

wrong answer. should be 0.2s

Ans 11:

Ans 16:

Class : Class 7
The answer seems to be wrong. 5 seconds to complete 25 oscillations. That means for one oscillation it is 5/25 = 0.2 seconds. 'Period' usually means one complete oscillation that is 0.2 seconds and that is not given.
